摘　　要：对采用流化床包膜技术制作的控释复合肥进行了一串红花卉盆栽试验,并与普通复合肥进行了肥效对比。经控释复合肥处理的一串红叶绿素相对含量、叶面积、叶数和生长势均比普通复合肥有明显优势。植株的平均干样质量和花样质量在各施肥处理上均显著大于普通复合肥。从观赏价值来看,与普通复合肥相比,控释复合肥处理的一串红开花早,花量多,鲜艳夺目。控释复合肥不仅在促进生长发育方面,而且在防止因施肥量过高造成植株伤害的安全性方面都具有明显的优越性。一串红在直径25cm、高21cm盆栽的控释肥最佳施肥量是纯N0.4g/kg土。The experiment of controlled-release fertilizers(CRFs) on growth and development of salvia plant in pot was conducted in comparison with common compound fertilizers (CCFs). The contents of chlorophyll, number of leaves, leaf area and growth potential of the salvia treated by CRFs were significantly greater than those by CCFs. There were higher dry matter mass and flower mass of salvia treated with CRFs compared with those by CCFs. Furthermore, the treatment with CRFs distinctly boosted florescence flourish and extended view period, which promoted salvia growth, but also avoided damage to the plants caused by excess use of fertilizers . The optimum amount for fertilizer application on salvia in the 25 cm×21 cm pot was N 0.4 g/kg soil.
